1.1This guide provides guidelines for the selection and training of expert assessors for the sensory evaluation of toothpaste and toothbrushes as well as a basic framework for the sensory evaluation of the same. Sensory evaluation of toothpaste and toothbrushes can be used to define the sensory attributes of the products and then to measure those attributes quantitatively for the purposes of new product development, product optimization, competitive benchmarking, and claims substantiation.

1.2A general framework for both toothpaste and toothbrush descriptive analysis is provided to guide the reader in the design and execution (including sample preparation and presentation, facility and testing environment, and specific evaluation protocols) for such evaluations.

1.3This guide provides suggested protocols and approaches to the evaluation of the indicated products/samples and in no way excludes any alternate approaches that may be effective in providing such perceptual evaluations.

1.4This guide does not address other oral care products including, but not limited to, whitening agents, oral rinses, mouthwashes, dental flosses, denture adhesive, floss picks, or other oral care products.

1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
